    • The restoration of melody perception is a key remaining challenge in cochlear implants. A novel sound coding strategy is proposed that converts an input audio signal into time-varying electrically stimulating pulse trains. A sound is first split into several frequency sub-bands with a fixed filter bank or a dynamic filter bank tracking harmonics in sounds. Each sub-band signal is coherently downward shifted to a low-frequency base band. These resulting coherent envelope signals have Hermitian symmetric frequency spectrums and are thus real-valued. A peak detector or high-rate sampler of half-wave rectified coherent envelope signals in each sub-band further converts the coherent envelopes into rate-varying, interleaved pulse trains. Acoustic simulations of cochlear implants using this new technique with normal hearing listeners, showed significant improvement in melody recognition over the most common conventional stimulation approach used in cochlear implants.
    • 耳蜗感知的恢复是耳蜗植入物中仍然存在的关键问题。 提出了一种新颖的声音编码策略,将输入音频信号转换为时变电刺激脉冲串。 声音首先被分割成具有固定滤波器组或动态滤波器组的几个频率子带,以跟踪声音中的谐波。 每个子带信号相干地向下移位到低频基带。 这些产生的相干包络信号具有埃米特对称频谱,因此是实值。 每个子带中的半波整流相干包络信号的峰值检测器或高速采样器进一步将相干包络转换成速率变化的交错脉冲串。 使用这种新技术与正常听力听众的耳蜗植入物的声学模拟显示出在耳蜗植入物中使用的最常见的常规刺激方法的旋律识别显着改善。
